Introduction: In the realm of modern APIs, the provision of clear and comprehensive documentation plays a pivotal role in facilitating developer adoption and ensuring efficient utilization. Swagger, aligned with the OpenAPI Initiative, stands out as a prominent solution, offering machine-readable documentation and a user-friendly interactive interface. In this guide, we'll delve into the seamless integration of Swagger into your .NET Core API. Step 1: Install the necessary packages Add Swashbuckle.AspNetCore NuGet package to a project: dotnet add package Swashbuckle.AspNetCore Add Swashbuckle.AspNetCore.SwaggerUI NuGet package to a project: dotnet add package Swashbuckle.AspNetCore.SwaggerUI Step 2: Add services in program.cs In the program.cs file, include the following service additions: builder.Services.AddEndpointsApiExplorer(); builder.Services.AddSwaggerGen(); Additionally, add middleware in program.cs to enable Swagger in the development environment:   if (app.Environment.IsDevelopment()) { app.UseSwagger(); app.UseSwaggerUI(); } Step 3: Run the API project and access the Swagger UI at: https://your-api-base-url/swagger Ensure the API project is running, and navigate to the provided URL to explore and interact with the Swagger UI seamlessly. Step 3:  Execute the APIs and test.  

Are you grappling with performance issues in your project? Look no further—Application Insights is here to help! In this blog post, I'll guide you through the process of configuring and implementing Application Insights to supercharge your application's performance monitoring. Step 1: Installing the Application Insights Package The first crucial step is to integrate the Application Insights package into your project. Simply add the following PackageReference to your project file: <PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.22.0" /> And Register service in Program.cs or Startup.cs : builder.Services.AddApplicationInsightsTelemetry(); builder.Services.ConfigureTelemetryModule<DependencyTrackingTelemetryModule>((module, o) => { module.EnableSqlCommandTextInstrumentation = true; }); Add connection string in appsettings.json :  "ApplicationInsights": {   "InstrumentationKey": "" } This sets the stage for a seamless integration of Application Insights into your application. Step 2: Unleashing the Power of Application Insights Now that the package is part of your project, let's dive into the benefits it brings to the table:  1. Identify Performance Bottlenecks Application Insights allows you to track the execution time of individual stored procedures, queries, and API calls. This invaluable information helps you pinpoint areas that require optimization, paving the way for improved performance.  2. Monitor Database Interactions Efficiently analyze the database calls made by specific APIs within your application. With this visibility, you can optimize and fine-tune database interactions for enhanced performance.  3. Comprehensive Error and Exception Tracking Application Insights goes beyond performance monitoring by providing detailed information about errors, traces, and exceptions. This level of insight is instrumental in effective troubleshooting, allowing you to identify and resolve issues swiftly.  Step 3: Integration with Azure for Data Collection and Analysis To maximize the benefits of Application Insights, consider integrating it with Azure for comprehensive data collection and analysis. This step amplifies your ability to make informed decisions regarding performance optimization and problem resolution. In conclusion, Application Insights equips you with the tools needed to elevate your application's performance. By identifying bottlenecks, monitoring database interactions, and offering comprehensive error tracking, it becomes a cornerstone for effective troubleshooting and optimization. Stay tuned for more tips and insights on how to harness the full potential of Application Insights for a high-performing application!
